Application filed July 23,

To all wwm may concern.'

Be itknown that l, LUTHER J. Inernnooit, a citizen of the United States,residing at Flowery Branch, in the county ci Hall and State of Georgia,have invented new and useful improvements in Flows, of which thefollowing is a speciiication.

This invention relates to reversible disk plows, and has ior its chiefcharacteristic the provision oi' means whereby the disks and t'urrowwheels are shifted or reversed to properly position the same withrespect to the ground when the plow is moved in a direction opposite tothat in which it was traveling.

The nature and advantages oi the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement oi parts as claimed.

in the drawings forming part of this application like numerals ot'reference indicate similar parts in the several views and wherein:

Figure 1 is a top plan view showing the position of the wheels and diskswhen the machine is moving in a direction indicated by the arrow.

Fig. 2 is a similar view showing the p0sition of parts when the machineis moving in a direction indicated by the arrow.

Fig. 3 s an enlarged sectional view taken on line 3 3 of Fig. 1.

Fig. l is a similar view taken on line /i-e of Fig. 2.

Fig. 5 is a similar view taken on line 5 5 of Fig. l.

Referring to the drawings in detail, indicates the main iframe of theplow, upon which are journaled the 'furrow wheels 11, and with which theland wheel trame 12 is connected, the land wheel being indicated at 13.The disks are indicated at 14; and are equipped with the usual disksegments 15 for the purpose to be hereinafter described` The plow may bedrawn over the ground surface by any suitable means, preferably by meansot a light tractor (not shown), the tractor being adapted to be coupledto either end of the tongue or beam 16 which projects an appreciabledistance beyond the opposite ends of the plow. The tongue or beam ismounted for sliding movement upon the land wheel frame, and operatesthrough Specification of Letters Patent.

suitable brackets 1T secured to the trame at the opposite ends thereof,these brackets supporting iter rotation all the rollers 18 whirhminimizes friction between the parts. Journaled for rotation immediatelyabove each disk is a gear 19 which measures with the toothedsegment 'forsaid disks, and also with a rack bar 2O secured to the tongue or beam1G. The tongue or beam 16 as above stated is mounted for slidingmovement through the brackets, but is limited in its movements inopposite direction by means ot' collars or stops 21 secured to thetongue or beam 16 at spaced points, these stops being disposed to engagethe frame at 12.

A lever 22 is pivoted at a point between its ends as at 23 to astationary member 211, the lever having an elongated slot 25 whichreceives a pin 26 projecting from the tongue or beam 16. Consequently,the lever 22 is moved upon its pivot through the instrumentality of thetongue or beam 16. Connected to the opposite end oi the lever are rods27 projecting in opposite directions and connecting the levers ot' thefurrow wheels, so that these wheels may be automatically operated in thewell known manner simultaneously with the shitting or reversing of thedisk 1d.

in practice, when the plow is being drawn in the direction of the arrowindicated in Fig. 1, one otl the stops 21 of the tongue or beam bearsagainst the adjacent ends of the frame 12, and the disks 14 held inproper position with respect to the ground when the plow is moving inthe direction indicated. When it is desired to plow in an oppositedirection, it is necessary of course to change the position of the disks14- and the spur wheels 11. The tractor is then uncoupled trom one endof the beam or tongue 16 and brought around to be coupled with theopposite end of said tongue or beam. Vlhen a vpull is exerted upon thebeam in the direction indicated by the arrow in Fig. 2, the tongue orbeam slides through the brackets 17 and guided by the rollers 18, untilthe other of the stops 21 is brought into engagement with the adjacentendet the i'rame as shown in Fig. 2. By this movement of the beam,rotation is imparted to the gears 19 by means of the rack bars 20, andas the wheels 19 rotate they automatically shift or reverse the disks1L1 in the position shown in Fig. 2, incident to the fact that the gearsare meshed with the segments 15. Simultaneously with the shifting of thedisks, the lever 22 is actuated in the manner described to shift thefurrow wheels 11.

While it is believed that from the oregoing description, the nature andadvantages of the invention will be readily apparent, l desire to haveit understood that I do not limit myself to what is herein shown anddescribed and that such changes may be resorted to when desired as tallwithin the scope of what is claimed.

What l claim is:

In a reversible disk plow, a frame, a pair of brackets secured to saidframe adjacent to the opposite ends thereof, spaced rollers rotatablymounted in said brackets, a draft tongue extending through said bracketsand engagingsaid rollers, a plurality of spaced collars secured to saidtongue and adapted t0 engage said frame, a lever pivotally secured tosaid frame and provided with an elongated slot, a pin projecting fromsaid tongue and engaging said slot, a plurality of disks pivotallysecured to said frame, spaced rackbars carried by said tongue, toothedsegments pivotally secured to said frame, and adapted to actuate saiddisks, gears meshing with said segments' and said bars, a plurality offurrow wheels pivotally secured to said frame and means engaging saidlever for shifting said furrow wheels simultaneously with the actuationof said disks.
